## What it does

This skill structures Substack content creation around two primary formats: inbox-focused newsletter issues and web-first essays for search and the internal feed. It separates personal writing from ghostwriting for a client. When ghostwriting, the agent requires extracting tone markers from transcripts or previous writing samples before drafting any copy. It builds a voice guide first.

The workflow enforces an interview stage before generating text. The agent stops and asks for your topic, target audience, format, word count, and conversion goal. It will not draft until you answer. Next, it proposes five subject lines and three hook options for selection. For generic technical blog posts lacking newsletter context, skip this skill in favor of `samber/cc-skills@technical-article-writer`. The prompts here focus strictly on subscription growth, Notes validation, and email conversion.

# Substack Ghostwriting & Content Optimization

A skill for writing Substack content — both newsletter issues (email-first) and web posts (web-first articles/essays) — that grows subscribers and converts readers. Handles two voice modes (own voice, ghostwriting) and two format modes (newsletter issue, web post).

## Core philosophy

Substack is not a blog with an email list. It's a social-media-newsletter hybrid with an algorithm that optimizes for subscriptions, not engagement. This changes everything about how you write, format, and distribute content on the platform.

The algorithm's incentives genuinely align with quality. Substack's revenue comes from subscription cuts (not ads), so gaming engagement metrics doesn't help. What helps: writing content good enough that readers convert to paid subscribers and recommend you to others.

For ghostwriting specifically: the job is capturing someone's existing insights in their voice, not generating insights from scratch. As Nicolas Cole frames it: clients are "insights-rich and time-poor", writers are "time-rich but insights-poor." The art is extraction and voice matching.

## Platform formatting constraints

Substack is a social-media-newsletter hybrid with an algorithm that optimizes for subscriptions, not engagement. Revenue comes from subscription cuts (not ads), so quality genuinely wins. For ghostwriting: the job is capturing someone's existing insights in their voice — clients are "insights-rich and time-poor."
